This processed failed for us and we were given a hint in the cron logs/output that the error was thrown at `htdocs/artefact/comment/blocktype/comment/lib.php:111`. Adding a `debug_print_backtrace()` to the file reveals more in the cron output: ``` [INF] 35 (lib/cron.php:190) Running core cron export_process_queue #0 PluginBlocktypeComment::render_instance_export(BlockInstance Object ([BlockInstanceid] => 320133,[BlockInstanceblocktype] => comment,[BlockInst............[truncated] , html) called at [<siteroot>/mahara/htdocs/lib/mahara.php:1818] #1 call_static_method(PluginBlocktypeComment, render_instance_export, BlockInstance Object ([BlockInstanceid] => 320133,[BlockInstanceblocktype] => comment,[BlockInst............[truncated] , html) called at [<siteroot>/mahara/htdocs/blocktype/lib.php:1351] #2 BlockInstance->render_viewing(html, ) called at [<siteroot>/mahara/htdocs/lib/view.php:2290] #3 View->build_column(3, 1, , html, ) called at [<siteroot>/mahara/htdocs/lib/view.php:2241] #4 View->build_columns(3, , html, ) called at [<siteroot>/mahara/htdocs/lib/view.php:2182] #5 View->build_rows(, html) called at [<siteroot>/mahara/htdocs/export/html/lib.php:479] #6 PluginExportHtml->dump_view_export_data() called at [<siteroot>/mahara/htdocs/export/html/lib.php:242] #7 PluginExportHtml->export() called at [<siteroot>/mahara/htdocs/export/lib.php:1015] #8 PluginExportAll->export() called at [<siteroot>/mahara/htdocs/export/lib.php:704] #9 export_process_queue() called at [<siteroot>/mahara/htdocs/lib/cron.php:198] [WAR] 35 (lib/errors.php:536) [Error]: Call to a member function get() on null at <siteroot>/mahara/htdocs/artefact/comment/blocktype/comment/lib.php:112 Call stack (most recent first): * exception(object(Error)) at Unknown:0 A nonrecoverable error occurred. This probably means you have encountered a bug in the system ``` We were able to fix it by explicitly declaring `global $exporter;` in `htdocs/export/lib.php:602` at the very start of the `export_process_queue` function - please refer to attached patch. It also affects portfolio exports when the "Export to queue" settings is enabled in Configure site > Site options > Account settings. ------------------------------ Application/System version(s): Mahara $config->version = 2020013013; $config->series = '20.04'; $config->release = '20.04.2'; OS Ubuntu 18.04.5 LTS DB MySQL 5.7 ------------------------------ To manage notifications about this bug go to: https://bugs.launchpad.net/mahara/+bug/1912705/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~mahara-contributors Post to : [email protected] Unsubscribe : https://launchpad.net/~mahara-contributors More help : https://help.launchpad.net/ListHelp
